TO ALL WHOM IT MAY' GONCERN: l

Be it known that I, FRANCIS W. B Ecnwlrn, of Westmoreland, inthe countyof Oneida, and State of .New Yorlghave invented new and usefulImprovements in Whiile-Tree Hooks; and I do hereby declarethat thefollowing is a full, clear, and exact description thereof, which willenable others-skilled in the art to'm'ake and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification.

Figure 1 is a. side view of my improved hook with aremoved sectionshowing the interior.

Figure 2 is au end view of the same. l l

Figure 3 is a cross-section of the hook through thc'line :t ce, fig. 1.

Similar letters of reference indicate corresponding parts. n

This invention consists of the combination' of the thimble andspring-tongue for obtaining a more safe and convenient hook forwhiHe-trees, as will4 be hereinafter more fully setAfo-rth.

Inthe accompanying plate of drawings,'A is the thi'mble', for` fittingon the end of a. whie-tree, and B the hook part of the same.'

The tongue, d, has its'meeting-end bevelled to {it the correspondingbeve'led part, h, of the hook B, which latter is cast on or otherwisefirmly aiixed to the thimble A, as shown. 'The tongue-is pivoted betweenlugs, m, by-a bolt or pivot, e, and is therefore permitted to be openedfrom th bevelle'd part t of the hook B. AThe oye of the tongue bearsaprojcictiomg, which impinges on a circular spring, a, within the end ofthe thiinble, andl is heldin placeby the circular bead g, andthe end oi'the thiu1ble,'as shown.

When the tongue is'pressed so as toppen the hook and'ndmit thebrace-hook or eye, the projectioni dcpresses that part of the circularspring, a, against which it irnpinges,` and-the projection, yafterhaving passedl beyondn certain point on the said spring, (which is thepoint where theline through pivot centre of thc tongue and the extremeend of the'projection z' is normal to the curve ofthe spring,) theaction ofthe spring is reversed, and it throws the tongue at'or nearlyat right angles to its {iist position; I I

When the trace is hooked' in, and-the tongue is pressed back to itsplacefor holding the trace within the hook, the tongue closes againstthe hook with a' -smart snap, and is held in that position, whereby thetrace cannot escape from the hook B. The acti-on of the projection z'and the spring a is somewhat analogous'to vthe actionof the anglesor-corners of a. clasp-lrnit`e blade audits spring.

Thijs invention is simple, durable, and notlilrcly to g'et out ofrepair, and prevents the trace from escaping from the hook, whichoccurrence was, with the wliiiHe-tree hook as heretofore made, veryfrequentand annoying.

I claim as new, and desire to secure by Letters Patent- The circularspring-band et, held against the end ofthe thimble by the bead g and thetongue h, having the projection pivote'd between the'lugs m, allconstr'ucted, arranged, and operating as described, whereby the `springis compressed at each outward and inward 'movement of the tongue, andthe latter held either open, or

closed by the outward expansion of saidv spring, asherein described, forthe purpose specified.

The above specification of my invention signed by me, this Gth'day ofJanuary', 1868.
